Grambling State plays its arch rival Southern University in the annual Bayou Classic, which is hosted at the Louisiana Superdome in New Orleans, Louisiana over Thanksgiving weekend and broadcast nationally on NBCSN. GSU also plays in the annual State Fair Classic against the Prairie View A&M Panthers at the Cotton Bowl, in Fair Park, in Dallas, Texas. Former football coachEddie Robinson previously held the NCAA record for most career wins as a head coach at an NCAA division I school. During Robinson's 55-year coaching career, the university gained a national reputation because of the large number of athletes who joined the professional ranks in football. After Robinson's retirement in 1997, former GSU standout and NFL Super Bowl XXII MVP Doug Williams took over the reins of the university's football program. Grambling has won fourteen black college national championships, tied for second most in the country. The 1981 TV movie Grambling's White Tiger set in 1967, tells the true story of Jim Gregory, the first white Quarterback at Grambling. In October 2013, citing health hazards within the Grambling State athletic facilities and team mismanagement in a letter to the administration, the Grambling State football team refused to play their October 19 game against Jackson St., forfeiting the match up, resulting in a loss. The NCAA would later go on to announce the ruling on the game was officially declared a no contest. The Tigers would return for their very next game a week later against Texas Southern.
Grambling State's colors are black and gold, with red as a tertiary color symbolizing the blood of people of African descent. The school's mascot is the Tiger. Grambling State's male athletes are traditionally referred to as "G-Men".
